As we saw in the last episode 1903 there are seven types of expansion applied to the command line in the following order:
There is also another, process substitution, which occurs after arithmetic expansion on systems that can implement it.
We will look at one more of these expansion types in this episode but since there is a lot to cover, we'll continue in a later episode.
I have written out a moderately long set of notes about this subject and these are available here http://hackerpublicradio.org/eps/hpr1951_full_shownotes.html.
This time, in the spirit of experimentation and as a way of learning Audacity I processed my audio thus:
Turned the stereo tracks to mono
Used a Noise Gate plug-in to reduce background noise (after "training" it on some silence)
Performed a Truncate Silence pass to reduce the length of pauses
Applied a small amount of amplification
Let me know if this had any positive or negative effects on the end product.
